I am trying to read/write from backup registers in STM32H7.Below is my code:__HAL_RTC_WRITEPROTECTION_DISABLE(hrtc); HAL_PWR_EnableBkUpAccess(); HAL_RTCEx_DeactivateTamper(hrtc, RTC_TAMPER_1); __HAL_RTC_TAMPER_CLEAR_FLAG(hrtc, RTC_FLAG_TAMP1F); ...
I have MCU STM32F103VET6, the microcontroller is clocked from HSI (internal 8MHz oscillator).Bun the frequency at the MCO pin is 6.4MHz. Why? I have the same MCU bought years ago, with the same code the frequency is correct - 8MHz. Here is my code:vo...
Hello,I've been attempting to get the full speed out of the ADCs in dual mode but seem to be limited to about 0.35msps. That is, when I sample a 10kHz wave, I only get 35 samples per period. I have attempted to change the adc and clock parameters in ...
MCU:STM32F0Discovery boardTools:STM32CubeMX+Keil5.30Test condition: PC_SerialComm tools & FT232 chip boardAfter trying the HAL_UART_RxHalfCpltCallback Function, I find that this function couldn`t be used in the normal transmit in UART_Comm.And would ...
My first results indicate that this library is faster and smaller. Unfortunately, I can not find any comparison with other libraries. It seems that this lib is not recognized outside of ST. So I am not sure whether I can trust this lib.
Hi!I designed my own development board with the STM32F205 microcontroller. But I can not find my processor via stlink and uart in any wayHow can I fix this problem?
Hello,I am using STM32L476RE and want to do XiP. So will it support XiP?Will the performance be good with running code from external memory?TIA
